I know you can post in forums to get silver, but are there any other ways to get currency? I don't really care what type, as long as I'm able to get it without paying IRL money.
If you check out the Battle Ground, that's a great way to earn silver. It might take a bit to get your fighting level to increase, but it's definitely worth it once you do.
I'd suggest getting a Healing Apple from the shops and a Crowbar to start off.
